Not available for separate purchase
We finally got a first look at Breath of the Wild‘sDLC. The first pack, The Master Trials is coming June 30, while the second pack, The Champions’ Ballad, is dated for Holiday 2017. They are only available if you buy the Expansion Pass; they can not be purchased individually.
One of the core game’s biggest issues was a lack of characterization, only getting snippets of these characters in the form of flashbacks. Hopefully Champions’ Balladwill provide some more depth to them.
